Update to original post of July 30, 2022 Rear brakes squeaking.
I reached out to my Ford Dealership via phone and then in person, and on October 10, 2022 the service department had the rear brake shoes/pad assemblies replaced, and the rear rotors machined, the Bronco had 10,150 miles at the time of repair. When I left the dealer the brakes worked as designed and the next morning there was no squeaking and the repair seem to have resolved the issue. I have just turned 14,100 miles and the rear brakes are still working without squeaking, as one would expect.
The service writer, Jesus and the service manager Jason Green were both professional and interested in getting this matter addressed which I appreciated. I’ll update my post should there be any issues moving forward.
